On a twins setup (hx35/40 16cm2NW, bht3b) what would be the better exhaust housing on the primary, a 20 or 26? I got both. And I was tryin to keep the twins stock headgasket friendly,(if there is such a thing) and mainly get my egt's down.

I also have the stock 12cm2W housing for the 35, as another option.

Anybody had any exp w/ this?

better go with the 26 to keep the boost down. but i bet you will need a big wastegate to keep it below 50.

 

another vote for 26..-jh

 

Thanks for the input fellas
